We cannot learn fear of God and the basic principles of godliness, unless we are pierced by the sword of the Spirit and destroyed. It is as if God were saying that to rank among his sons our ordinary natures must be wiped out.
— John Calvin
So tenaciously should we cling to the world revealed by the gospel, that were I to see all the angels of heaven coming down to me to tell me something different, not only would I not be tempted to doubt a single syllable, but I would shut my eyes and stop my ears, for they would not deserve to be either seen or heard.
— Martin Luther
